Introduction
Meech Ionised Air Curtains have unique static elimination capabilities and will give
many years of excellent service, provided that the following instructions are observed
closely.
4
General Notes On Operation
The typical Meech air curtain installation consists of one or more ionised air curtains
connected to a Meech power unit.

Introduction
General Notes On Operation
The static eliminator bar may be either an RML Model 910 (Green) or an HER Model
920 (Red). This bar converts the energy from the power unit to generate an ionised air
corona.The corona is transported to the object by the air ow.
5
When a statically charged object enters the ionised air corona, the free moving ions
are attracted to the opposite charge on the object. In this way the static electricity is
neutralised. Unused ions in the corona recombine or are discharged to earth.

Installation
The correct positioning of the air curtain is vital to its efcient operation. Please
observe the following instructions.
Distance From The Object
The air curtain should be positioned as close as possible to the object to be
neutralised.
If we say that the neutralisation power at a distance of 10cm is 100% then the relative
neutralisation performance at a longer distance is:
Distance From Object Relative Performance
30 cm
50 cm
100 cm
90 %
50 %
20 %
Intervening Objects
If the ionised air is blown through earthed objects eg a machine frame or cross rods,
these will absorb some of the ionisation and so reduce the neutralisation power. Avoid
this where possible.

Air Supply
a. The air supply must be clean and dry. A 5 micron coalescing lter is
recommended. The Meech guarantee does not cover damage due to water
or oil in the air supply.
b. Reduce the air supply to the lowest pressure which achieves the required
results. Excessive air is wasteful and also dilutes the ionisation
unnecessarily.
c. The female thread for the air tting is 1/4 BSP.
Air Pressure Comsumption
Per 150mm
Volume Out
Per 150 mm
Air Speed
1 bar 238 lit/min 5950 lit/min 250 m/min
2 bar 336 lit/min 8400 lit/min 530 m/min
3 bar 448 lit/min 11200 lit/min 848 m/min
4 bar 500 lit/min 11400 lit/min 1363 m/min
Caution: When used in conjunction with a model 920 HER ionising bar this
equipment will give an electrical shock if the pins are touched. The following
procedure must be followed.
The supply voltage of the power supply must be interlocked with the ON/OFF
control of the machine to which the equipment is tted.
This will ensure that whilst the machine is switched off and thus operatives may
gain access to the machine and our equipment there will be no danger of operatives
receiving shocks from our equipment.
It is assumed that normal safety barriers are in place on the machine to ensure that
operatives are unable to access the machine and hence our equipment whilst the
machine is switched ON.

CE Approval
A CE Declaration of Conformity for this product exists in respect of the Low Voltage
Directive:72/23/EEC (“LVD”) & Electrtomagnetic Compatibility Directive: 89/336/EEC
(“EMCD”)
Health and Safety
Emission of Ozone: Considerably below international standard of 0.1ppm.

Maintenance
Cleaning your Meech Ioniser
Ionisers require periodic cleaning. During normal operation, dirt will build-up on
the emitter pins and upon the body of the ioniser. This will cause a reduction in
performance.
Typically, weekly cleaning is sufcient. However, equipment used in some heavy
contamination areas, such as gravure printing or where plastic fumes are present, may
require daily cleaning. Equally, in a Class 100 area, cleaning may only be required
on a monthly basis. Advanced systems with performance monitoring, e.g 977cm and
904cm, will alert the operator to the need to clean the equipment before performance
drops to an unacceptable level.
Before cleaning, ensure that the equipment is switched off.
Emitter pins can be cleaned very effectively with a brush. A dry toothbrush is ideal.
Ionising bars will need periodic wiping to clean grey deposits from the surface
of the bar. A cloth moistened with a small amount of IPA or methylated spirits is
recommended.
